The impeller of 100-YQH multistage axial-flow pump, it is belonged to shed a calculative one part. When building a model to impeller, of the basis is the wooden model attempt of impeller, and the wooden model attempt that give out is to use many as homocentric as impeller but the fictitious cylinder face of different radius, go the plane of figure of cut lamina earnings spreads out graph; accordingly, when building a model, develop these plane the graph to restore these homocentric and columnar faces to go up afresh with respect to need, must undertake coordinate alternates first at this moment, when will foregone planar coordinate alternates coordinate of columnar coordinate; alternates, according to foregone columnar face radius, use chord to be equal to the relation computation coordinate of arc length, z coordinate keeps changeless. Of the dot generate: Above all, make the homocentric round cylinder of different radius, input the coordinate that coordinate nods on the wing section of commutation earning next, bit of; is generated on columnar face the type of these dots must be fictitious (namely Virtual) , cannot be bit solidder (namely Real) . Because be in the following commutation, some commands are the; that cannot operate to real point and if want to nod empty later,changeover becomes real point, gambit has the order that implements this kind of function, but command without contrary operation however. Of line segment generate: Select the type of unripe set prescription of the line and kind, the choice generates Real NUBS curve, nod thread repeatedly next. Attention: At this moment although the dot is in on columnar face, but these lines however may not is on columnar face. Of the face generate: Above all, should check line segment to whether join composition closes 1 times together face. If line segment did not close, choose jumper command to make line segment closes; at this moment, may discover a few redundant line segment, but delete directly do not drop (the likelihood is citing because of other substance) , need to return join to choose an order so, pass join 2 end points of this line segment, delete this line segment. Check line segment close after the gender, can generate face; with these line segment but these line segment are not on columnar face, then, be about to be the range that will make to choose a generatrix (namely a Host, choose corresponding columnar face) , give tolerance, so that Gambit makes the range that is apart from generatrix to be less than tolerance automatically,be on generatrix. According to afore-mentioned measure, fictitiousing range is made in different round cylinder hind, delete these fictitiousing faces again, but the line segment that reservation constitutes these faces, and these line segment as it happens are located in on columnar face, and join each other. Make a range with these line segment next, these faces are the outside face of blade. CNC Milling CNC Machining
